The Scott Alpha 20 is a power amplifier that was manufactured from 1977 to 1979 in Japan. It is characterized by its silver color and offers a robust performance for audiophiles. The amplifier features a single Line In connection with a sensitivity of 1.5 V and an impedance of 47 kOhm, along with two loudspeaker outputs. It delivers continuous power of 200 W RMS per channel under 8 Ohms at a total harmonic distortion (THD) of less than 0.1% within the frequency range of 20Hz to 20kHz. At 4 Ohms, the dynamic power capabilities are also commendable. The total harmonic distortion is impressively low at 0.015% at rated power. This model boasts an attenuation factor of 100 at 8 Ohms and a frequency response extending from 5 Hz to 60 kHz, ensuring a wide range of audio fidelity. The signal-to-noise ratio is rated at 105 dB, indicating a clean output with minimal background noise. Special features include channel-separated level controls and a dedicated power display for left and right channels. It has dimensions of 495 x 153 x 318 mm and weighs 18.6 kg, making it relatively compact for a power amplifier, yet sturdy. Its original price was approximately $750 USD or 1,750 DM.
